Abstract
This disclosure relates generally to thermal management fluids. More particularly this disclosure relates to a dielectric thermal management fluid suitable for use managing heat in battery systems through direct cooling, such as lithium-ion batteries used in electric vehicles, electric motors, and power electronics, methods of using such thermal management fluids, and systems including such thermal management systems.
Claims20
A thermal management fluid comprising:
- one or more dielectric compounds of formula (I):
- wherein
- n is an integer 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12;
- m is an integer 1, 2, or 3;
- R1 is C1-C5 alkyl;
- R2 is C1-C5 alkyl;
- each R3, R4, R5, and R6 are independently selected from H, C1-C8 alkyl, and R7O—(CH2)0-1—, wherein R7 is C1-C5 alkyl,
- provided no more than two of R3, R4, R5, and R6 are R7O—(CH2)0-1—;
- the one or more dielectric compounds being present in a total amount in the range of 1 wt % to 100 wt %, based on the total weight of the thermal management fluid;
- and
- wherein the thermal management fluid has a flash point of at least 100° C., measured in accordance with ASTM D93, and the thermal management fluid has a dielectric constant of at least 1.5 at 25° C.
